The theory of transmission lines is a classical topic of electrical engineering. Recently this topic has received renewed attention and has been a focus of considerable research. This is because the transmisson line theory has found new and important applications in the area of high-speed VLSI interconnects, while it has retained its significance in the area of power transmission. In many applications, transmission lines are connected to nonlinear circuits. For instance, interconnects of high-speed VLSI chips can be modelled as transmission lines loaded with nonlinear elements. These nonlinearities may lead to many new effects such as instability, chaos, generation of higher order harmonics, etc. The mathematical models of transmission lines with nonlinear loads consist of the linear partial differential equations describing the current and voltage dynamics along the lines together with the nonlinear boundary conditions imposed by the nonlinear loads connected to the lines. These nonlinear boundary conditions make the mathematical treatment very difficult. For this reason, the analysis of transmission lines with nonlinear loads has not been addressed adequately in the existing literature. The unique and distinct feature of the proposed book is that it will present systematic, comprehensive, and in-depth analysis of transmission lines with nonlinear loads. A unified approach for the analysis of networks composed of distributed and lumped circuits A simple, concise and completely general way to present the wave propagation on transmission lines, including a thorough study of the line equations in characteristic form Frequency and time domain multiport representations of any linear transmission line A detailed analysis of the influence on the line characterization of the frequency and space dependence of the line parameters A rigorous study of the properties of the analytical and numerical solutions of the network equations The associated discrete circuits and the associated resisitive circuits of transmission lines Periodic solutions, bifurcations and chaos in transmission lines connected to noninear lumped circuits

Readers gain a thorough understanding of the properties of planar transmission lines for integrated circuits. Moreover, this practical book presents matrix and computer-aided methods for analysis and design of circuit components.

The primary objective of this work has been to derive a lumped circuit model for the lossless (or low loss) transmission line which yields accurate output voltages regardless of the type of line termination. The model is developed by synthesizing a lumped circuit exhibiting Z-parameters which are the same as those for the distributed parameter transmission lines. (Author).

A comparison between the predictions of various lumped-circuit iterative models of transmission lines and that of the transmission line model is given for both the two and three-conductor cases.

A comparison between the predictions of various lumped-circuit iterative models of transmission lines and that of the transmission line model is given for both the two and three-conductor cases. For frequencies such that the line length is approximately 1/10 of a wavelength or less one section of the lumped-circuit models yield predictions which are within +3dB of the transmission line model predictions, and which are essentially independent of the value of load impedance. For frequencies where the line length is greater than approximately 1/10 of a wavelength, more than one section of the lumped models must be used to yield accurate predictions, but the prediction accuracy may be significantly effected by the load impedance value. The range of accurate predictions (in terms of electrical length) may be increased by adding more sections of a lumped-circuit model, but this range increases in a nonlinear fashion. Because of this nonlinear relationship, it is difficult to find a satisfactory method for estimating the number of sections of a particular lumped-circuit model that must be used in order to obtain a desired range of accurate predictions.

This book presents the topic of Transmission-Line Modeling (TLM) to a graduate or advanced undergraduate audience. It will also be suitable for computational electromagnetics specialists working in industry who wish to become familiar with this technique.Author Christos Christopoulos emphasizes the technique's physical concepts before embarking on a discussion of its mathematical developments. The work also provides simple straightforward suggestions for the development of models, which can then be programmed for further computation. Also included are sections with a strong mathematical flavor where there are clear methodological advantages, forming the basis for developing practical modeling tools. The main implementation of TLM is as a time-domain differential equation method but there are also TLM implementations in the frequency-domain. The emphasis of this book is on the time-domain TLM.

The essential textbook for electrical engineering students and professionals-now in a valuable new edition The increasing use of high-speed digital technology requires that all electrical engineers have a working knowledge of transmission lines. However, because of the introduction of computer engineering courses into already-crowded four-year undergraduate programs, the transmission line courses in many electrical engineering programs have been relegated to a senior technical elective, if offered at all. Now, Analysis of Multiconductor Transmission Lines, Second Edition has been significantly updated and reorganized to fill the need for a structured course on transmission lines in a senior undergraduate- or graduate-level electrical engineering program. In this new edition, each broad analysis topic, e.g., per-unit-length parameters, frequency-domain analysis, time-domain analysis, and incident field excitation, now has a chapter concerning two-conductor lines followed immediately by a chapter on MTLs for that topic. This enables instructors to emphasize two-conductor lines or MTLs or both. In addition to the reorganization of the material, this Second Edition now contains important advancements in analysis methods that have developed since the previous edition, such as methods for achieving signal integrity (SI) in high-speed digital interconnects, the finite-difference, time-domain (FDTD) solution methods, and the time-domain to frequency-domain transformation (TDFD) method. Furthermore, the content of Chapters 8 and 9 on digital signal propagation and signal integrity application has been considerably expanded upon to reflect all of the vital information current and future designers of high-speed digital systems need to know. Complete with an accompanying FTP site, appendices with descriptions of numerous FORTRAN computer codes that implement all the techniques in the text, and a brief but thorough tutorial on the SPICE/PSPICE circuit analysis program, Analysis of Multiconductor Transmission Lines, Second Edition is an indispensable textbook for students and a valuable resource for industry professionals.
